9 A Pla&orm for System Analysis and Research Digital beamforming is a promising further improvement for future mmw architectures Ini$al Access (IA) IA latency increases with increasing array size Beam management protocols addressed in 3GPP NR to reduce overhead, power and latency Digital beamforming can further reduce latency over analog Radio Link Failure (RLF) mmw connec$on may result in more frequent RLF due to severe non-line-of-sight losses RLF detec$on performance is superior in a Non-Standalone architecture (LTE-Overlay) as compared to Stand-Alone (SA) Digital beamforming can improve RLF reac$veness These results are a result of a research collabora$on between InterDigital and University of Padua/Consorzio Futuro in Ricerca.
